| All-new K3 engine has a more linear power delivery, with higher top-end RPM compared to the K5. We recommend using the 2131 muffler, which was specifically designed for the K3 engine. The K3 is a premium, high-performance 1/8 off-road engine designed for high-competition racing. Features include: 3 ports, silicone-filled diamond-coated crankshaft, premium Japanese front bearing, and ceramic German rear bearing. The K3 is an extremely reliable and powerful engine suitable for any race track and racing conditions. All the finest engineering and craftsmanship has gone into the concept, design, creation, and finishing of FX Engines. This engine and all of its parts were designed and manufactured by FX in-house in Slovakia, Europe from the finest European materials and using the most advanced Swiss, German, and Italian technologies. Even the crankcase was die cast in-house using fully-robotic die-casting technology. All parts are individually measured and inspected, and all dimensions are recorded to ensure a full manufacturing & assembly record of every single part. Each engine includes a manufacturing certificate that records all important serial numbers and measurements so that, at any time, all details of the production –material batch, machine programs, responsible craft persons and production dates – can be traced back to the beginning.
